This phase II Pediatric MATCH trial studies how well ensartinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with ALK or ROS1 genomic alterations that have come back or do not respond to treatment and have spread to other places in the body. Ensartinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase II Pediatric MATCH trial studies how well erdafitinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders that have spread to other places in the body and have come back or do not respond to treatment with FGFR mutations. Erdafitinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This phase II Pediatric MATCH trial studies how well olaparib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with defects in deoxyribonucleic acid (DNA) damage repair genes that have spread to other places in the body and have come back or do not respond to treatment. Olaparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase II Pediatric MATCH trial studies how well selumetinib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with MAPK pathway activation mutations that have spread to other places in the body and have come back or do not respond to treatment. Selumetinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.

This phase II Pediatric MATCH trial studies how well vemurafenib works in treating patients with solid tumors, non-Hodgkin lymphoma, or histiocytic disorders with BRAF V600 mutations that have spread to other places in the body and have come back or do not respond to treatment. Vemurafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase II Pediatric MATCH trial studies how well tazemetostat works in treating patients with solid tumors, non-hodgkin lymphoma, or histiocytic disorders that have spread to other places in the body and have come back or do not respond to treatment and have EZH2, SMARCB1, or SMARCA4 gene mutations. Tazemetostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
